Measurement principle

on-the-fly measurement
The principle of "on-the-fly" measurement is implemented in the SINUMERIK control. The
probe signal is processed directly on the NC so that the delay when acquiring measured
values is minimal. This permits a higher measuring speed for the prescribed measuring
precision and time needed for measuring is reduced.
Connecting probes
Two inputs for connecting touch trigger probes are provided on the I/O device interface of
the SINUMERIK control systems.
